Description

Vibration welding molded article, vibration welding device, and method for manufacturing vibration welding molded article
Technical Field
The present invention relates to a vibration welding molded article obtained by vibration welding a plurality of resin members, a vibration welding apparatus for obtaining a vibration welding molded article, and a method for manufacturing a vibration welding molded article.
Background
For example, a resinous member called a tailgate spoiler may be provided at an upper portion of a tailgate provided at a rear portion of a vehicle. As an example, a vibration welded molded article obtained by vibration welding a plurality of resin members is used as the tail gate spoiler. As a conventional technique related to such a vibration welded molded product, there is a technique disclosed in japanese patent application laid-open No. 2010-208058.
The vibration welding molded article shown in japanese patent application laid-open No. 2010-208058 includes: an outer member including a substantially V-shaped portion; and an inner member disposed inside the substantially V-shaped portion of the outer member, and vibration-welded to the outer member.
The outer member has a substantially plate-shaped base surface portion and a slope portion formed obliquely to the base surface portion and opposed to the base surface portion. The inner member has a first joint surface portion vibration-welded to the base surface portion, and a second joint surface portion vibration-welded to the inclined surface portion.
In vibration welding, vibration is applied while pressing the first joining face portion toward the base face portion, and the inclined face portion is pressed toward the second joining face portion.
By integrating the 2 members by vibration welding, an adhesive or the like is not required, and high appearance can be ensured.
Disclosure of Invention
The tail gate spoiler disclosed in japanese patent application laid-open No. 2010-208058 is provided at the upper rear end of the vehicle, and therefore has high visual confirmation from the subsequent vehicle. Therefore, in some vehicles, it is considered that an opening is provided in a slope portion of an outer member, and a brake lamp is provided in the opening.
In this case, it can be seen that: when the inclined surface portion is pressed by an assist tool (assist tool) as disclosed in japanese patent application laid-open No. 2010-208058, the following problems may occur. The strength of the inclined surface portion is reduced by the formation of the opening. Therefore, when welding is performed while pressing the inclined surface portion with the aid, the inner member may not be sufficiently welded to the outer member due to large deflection of the inclined surface portion or the like.
In the vibration welding formed article having the opening, it is preferable that the inner member is welded to the outer member with high strength, not limited to the tail gate spoiler.
The present invention provides a technique capable of welding an inner member to an outer member with high strength.
According to the present disclosure, there is provided a vibration welding formed article having: an outer member including a substantially V-shaped portion; and an inner member disposed inside the substantially V-shaped portion of the outer member and vibration-welded to the outer member,
wherein,
the outer member includes: a substantially plate-like base portion; and a slope portion formed obliquely to the base surface portion and opposed to the base surface portion,
the inclined surface part is provided with an outer part opening part which is opened in a mode of being capable of installing other parts,
the inner member includes: a first joint surface portion vibration-welded to the base surface portion; a second joint surface portion vibration-welded to the inclined surface portion; and a protrusion protruding from the second engaging surface portion toward the base surface portion.

In the description, the right and left refer to the right and left with respect to the occupant of the vehicle, and the front and rear refer to the front and rear with respect to the traveling direction of the vehicle. In the figure, fr denotes the front, rr, le denotes the left when viewed from the occupant, ri denotes the right when viewed from the occupant, up, dn denotes the lower.
Example 1 ]
Reference is made to fig. 1 and 2. A tail gate spoiler 10 (hereinafter, simply referred to as spoiler 10) as a vibration welded formed article 10 is provided at the upper portion of the rear end of the vehicle Ve. The spoiler 10 is attached to the vehicle body Bo for the purpose of improving aerodynamic characteristics of the vehicle Ve and improving design.
The spoiler 10 extends rearward continuously from the upper portion of the rear end of the vehicle body Bo, and is provided throughout the vehicle width direction. A rear glass Rg is provided below the spoiler 10.
Refer to fig. 2. The spoiler 10 has: an outer member 20 including a substantially V-shaped portion; and an inner member 30 that is disposed inside the substantially V-shaped portion of the outer member 20 and is vibration-welded to the outer member 20.
The spoiler 10 is provided with a brake lamp SI (hereinafter simply referred to as a lamp SI) as another component SI. The lamp SI is turned on when the brake is in operation for the subsequent vehicle identification to be in deceleration.
The outer member 20 is a resin design member that can be visually checked from the outside of the vehicle Ve. The outer member 20 has: a substantially plate-shaped base portion 21 extending rearward continuously from a ceiling of the vehicle body Bo; a slope 22 formed obliquely to the base 21 and facing the base 21; and a connecting portion 23 that connects the base portion 21 and the inclined surface portion 22.
The inclined surface portion 22 is provided with an outer member opening 22a so as to be able to mount the lamp SI. The inclined surface portion 22 is inclined at 20 ° with respect to the base surface portion 21, for example. The angle is preferably 30 ° or less. The reason is described later.
The inclination angles of the inclined surface portion 22 and the connecting portion 23 with respect to the base surface portion 21 are different. The inclined surface portion 22 may extend from the end of the base surface portion 21 without the connection portion 23.
The inner member 30 has: a first joint surface portion 31 vibration-welded to the base surface portion 21; a standing wall portion 32 standing from the first joint surface portion 31 toward the inclined surface portion 22; a second joint surface portion 33 extending from the standing wall portion 32 along the inclined surface portion 22 and vibration-welded to the inclined surface portion 22; an auxiliary wall portion 34 extending from the second joint surface portion 33 toward the base surface portion 21; an auxiliary leg 35 extending from the auxiliary wall 34 along the base surface 21; and a protrusion 36 protruding from the second engaging surface portion 33 toward the base surface portion 21.
Refer to fig. 3A. The inner member 30 also has a plurality of ribs 37, the ribs 37 connecting the auxiliary wall portion 34 and the auxiliary leg portion 35.
The left and right end portions of the first engaging surface portion 31 protrude forward, and the other portions of the first engaging surface portion 31 are formed to have substantially the same front-rear width. A plurality of projections (welding ribs) having a small height may be formed on the surface of the first joint surface portion 31 that abuts against the base surface portion 21 (see fig. 2) in order to promote vibration welding.
Referring to fig. 2 together. The standing wall portion 32 is inclined rearward with respect to a surface standing upright from the base surface portion 21 and the first engaging surface portion 31. The standing wall portion 32 has an inner member opening 32a, and the inner member opening 32a is opened at a position facing the outer member opening 22a.
The inner member opening 32a is a substantially rectangular opening long in the left-right direction. The inner member opening 32a is formed only at a portion of the standing wall 32 facing the lamp SI. When the height from the base surface portion 21 is taken as a reference, at least a part of the inner member opening 32a is formed at the same height as the outer member opening 22a.
Referring to fig. 2 and 3B. The front-rear width of the portion of the second joint surface 33 where the lamp SI is arranged is narrower than the front-rear width of the other portions. A plurality of projections (welding ribs) having a small height may be formed on the surface of the second joint surface portion 33 that abuts against the inclined surface portion 22 in order to promote vibration welding. The second engagement surface portion 33 formed along the inclined surface portion 22 is inclined at 20 ° with respect to the base surface portion 21, for example.
Referring to fig. 2 and 3A. The portion of the auxiliary wall 34 where the lamp SI is disposed is recessed toward the front. Referring to fig. 4, a plurality of auxiliary wall openings 34a and 34b having different shapes are formed in the auxiliary wall 34. The distal end of the protruding portion 36 can be visually confirmed from the auxiliary wall opening 34a formed in a substantially rectangular shape. The auxiliary wall opening 34b formed in a circular hole shape is, for example, a hole for fixing a mounting portion provided to the lamp SI (see fig. 2) by a fastening member, and a hole for inserting a positioning shape (a cross pin or the like) provided to the lamp SI.
The auxiliary wall opening 34a is formed only at a portion of the standing wall 32 facing the lamp SI. When the height from the base surface portion 21 is taken as a reference, at least a part of the auxiliary wall opening 34a is formed to have the same height as the outer member opening 22a and the inner member opening 32a.
Referring to fig. 3A and 3B. The auxiliary leg 35 is formed to have a wide width in the front-rear direction only in a portion above the lamp SI (see fig. 2).
The auxiliary leg 35 may be vibration-welded to the base surface portion 21 (see fig. 2), or may not be vibration-welded. The spoiler 10 can be reinforced with the auxiliary wall portions 34 and the auxiliary leg portions 35.
The protrusions 36 are formed parallel to each other so as to extend in the front-rear direction. Referring to fig. 2 together. The plurality of protrusions 36 may be formed along the direction in which the slope surface portion 22 extends from the base surface portion 21. There is no fear that water droplets or the like that have entered from the auxiliary wall opening 34a accumulate at the joint where the second joint surface 33 and the protrusion 36 are joined.
As shown in fig. 2 in particular, the distal end surface 36t of the protrusion 36 is formed substantially parallel to the base surface 21. On the other hand, the distal end face 36t of the protrusion 36 is inclined with respect to the second engaging face 33. As described above, in the case where the second joining face portion 33 is inclined by 20 ° with respect to the base face portion 21, the distal end face 36t substantially parallel to the base face portion 21 is inclined by substantially 20 ° with respect to the second joining face portion 33.
When a virtual plane substantially parallel to the base surface from the lower edge 22u of the outer member opening 22a is defined as the reference surface Bs, the projection 36 projects to a position closer to the base surface 21 than the reference surface Bs. In other words, when a virtual plane substantially parallel to the base surface portion 21 from the edge closest to the second joint surface portion 33 among the edges of the outer member opening portion 22a is set as the base surface Bs, the protruding portion 36 can protrude to a position closer to the base surface portion 21 than the base surface Bs.
The direction and number of the projections 36 and the shape of the projections 36 can be arbitrarily set.
Referring to fig. 3A together. By forming the rib 37, deformation of the outer member 20 and the inner member 30 when the base surface portion 21 and the inclined surface portion 22 are pressed can be suppressed.
Next, a vibration welding method of the inner member 30 to the outer member 20 will be described.
Refer to fig. 5. A vibration welding apparatus 40 for performing vibration welding will be described. In addition, when vibration welding is performed, the outer member 20 is placed below and the inner member 30 is placed above. I.e. upside down as shown in fig. 2.
The vibration welding apparatus 40 includes: a support die 41 that mounts the outer member 20 and is movable up and down; a vibration-applying die 42 that presses the first joint surface portion 31 toward the base surface portion 21 and vibration-welds the first joint surface portion 31 to the base surface portion 21 by generating vibration; a pressing die 43 provided so as to be capable of swinging toward the inclined surface portion 22 and pressing the inclined surface portion 22 toward the second engagement surface portion 33; and a movable die 44 provided so as to be linearly movable from the outer member opening 22a toward the protruding portion 36 and so as to be capable of abutting against the protruding portion 36.
In vibration welding, first, the outer member 20 and the inner member 30 are set on the upper surface of the support die 41, and then the support die 41 is raised. The support die 41 is raised to a position where the first joint surface portion 31 abuts against the vibration die 42. Next, the movable die 44 is moved from the outer member opening 22a, and the upper surface of the movable die 44 is moved to a position facing the protrusion 36. At this time, the moving die 44 moves substantially perpendicular to the moving direction of the supporting die 41. Then, the pressing die 43 is swung to come into contact with the inclined surface portion 22.
In this case, a slight gap may be provided between the protrusion 36 and the movable die 44. As described above, the welding rib is sometimes formed on the first joint surface part 31. Therefore, the inner member 30 floats by an amount corresponding to the height of the welding rib, and a slight gap may be generated between the distal end surface 36t of the protrusion 36 and the movable die 44. Further, by bringing the base surface portion 21 into close contact with the first joint surface portion 31, a gap may be slightly generated between the distal end surface 36t of the protrusion 36 and the movable die 44 by an amount corresponding to the dimensional error. That is, when the inner member 30 is welded to the outer member 20, the state in which the inclined surface portion 22 and the protruding portion 36 are held includes a state in which a slight gap exists between the protruding portion 36 and the movable die 44.
The base surface portion 21 and the first engaging surface portion 31 are held by a support die 41 and a vibration die 42, and the inclined surface portion 22 and the second engaging surface portion 33 are held by a pressing die 43 and a moving die 44. In this state, the vibration mode 42 is operated. Friction heat is generated at the abutment portion where the base surface portion 21 abuts against the first joining surface portion 31 and the abutment portion where the inclined surface portion 22 abuts against the second joining surface portion 33 by the vibration transmitted from the vibration applying die 42. By this heat, the contact portion where the base surface portion 21 contacts the first joint surface portion 31 and the contact portion where the inclined surface portion 22 contacts the second joint surface portion 33 are welded, respectively. The spoiler 10 is finished by welding.
At the time of vibration welding, the inclined surface portion 22 and the second joint surface portion 33 may be deflected downward. At this time, the distal end surface 36t of the protrusion 36 abuts against the movable die 44. This can suppress the large deflection of the inclined surface portion 22 and the second joint surface portion 33.
Further, the inclination of the second joint surface portion 33 with respect to the base surface portion 21 is more preferably 30 ° or less. When it exceeds 30 °, the pressing force of the pressing die 43 may not be sufficiently transmitted in a direction of pressing the inclined surface portion 22 against the second engaging surface portion 33. If the pressing force is not sufficiently transmitted, the second joint surface 33 cannot be welded to the inclined surface 22.
The movable die 44 may be inserted from the outer member opening 22a before or simultaneously with the raising of the support die 41. When the movable die 44 is inserted in a state in which the base surface portion 21 and the first engaging surface portion 31 are sandwiched between the support die 41 and the vibration die 42, the displacement of the inner member 30 in a case in which the movable die 44 interferes with the protruding portion 36 at the time of insertion can be prevented, which is more preferable.
The spoiler 10 described above can obtain the following effects.
The spoiler 10 has a protrusion 36, and the protrusion 36 protrudes from the second engagement surface portion 33 toward the base surface portion 21. When the inclined surface portion 22 is pressed, the pressing from the second joint surface portion 33 side is also possible, and therefore, the outer member 20 and the inner member 30 can be restrained from being deflected. Here, in the case where the protrusion 36 is not provided, the second engaging surface 33 needs to be directly pressed. However, in this case, there is a possibility that the edge of the outer member opening 22a or the like interferes with each other, and the second joint surface 33 cannot be sufficiently pressed. According to the spoiler 10, the second joint surface portion 33 side can be easily supported by having the protruding portion 36. Therefore, the inner member 30 can be welded to the outer member 20 with high strength.
Further, it is preferable that a guide surface portion 36g serving as a guide is formed on the outer member opening portion 22a side of the protrusion portion 36. That is, the protrusion 36 has a guide surface 36g, and the guide surface 36g is formed obliquely from the second engagement surface 33 toward the distal end surface 36 t. The guide surface 36g is formed obliquely with respect to a surface perpendicular to the distal end surface 36 t. Thereby, the movable die 44 can be guided toward the distal end surface 36 t.
In addition, even when vibration welding is performed using a device other than the vibration welding device 40, by providing the protrusion 36, it is possible to easily support from the second joint surface portion 33 side. Therefore, by forming the protruding portion 36 in the spoiler 10, the inner member 30 can be welded to the outer member 20 with high strength.
Referring to fig. 2 together. The standing wall portion 32 has an inner member opening portion 32a opened at a position opposed to the outer member opening portion 22a. The lamp SI can be attached from the side of the inner member opening 32a. The movable die 44 can be inserted from the side of the inner member opening 32a. The assembling work of the spoiler 10 can be easily performed. In addition, even when the rigidity of the standing wall portion 32 supporting the pressing of the inclined surface portion 22 is reduced during vibration welding, the inner member 30 can be welded to the outer member 20 with high strength, and the degree of freedom in design can be improved.
Further, the protruding portion 36 protrudes to a position closer to the base surface portion 21 than the base surface Bs. This makes it possible to more easily support the second joint surface 33 side during vibration welding. The inner member 30 is particularly preferably welded to the outer member 20 with high strength.
Further, the distal end face 36t of the protrusion 36 is formed on a face intersecting the second engaging face. The protruding direction of the protruding portion 36 is substantially the same as the direction in which the base surface portion 21 and the first joining surface portion 31 are sandwiched by the support die 41 and the vibration die 42. In this way, the second engaging surface portion 33 side can be easily supported. In addition, simplification of the movable die 44 and the support die 41 and design freedom are also improved.
The protrusions 36 are formed in parallel to each other at a plurality of positions. By supporting the outer member 20 and the inner member 30 at a plurality of positions, deformation of the outer member can be further suppressed. The inner member can be welded to the outer member with higher strength.
The movable die 44 is provided, and the movable die 44 is provided so as to be movable from the outer member opening 22a toward the protruding portion 36 and so as to be capable of abutting against the protruding portion 36. By allowing the movable die 44 to come into contact with the protrusion 36, the second joint surface 33 can be supported when the inclined surface 22 is pressed. This enables the inner member 30 to be welded to the outer member 20 with high strength.
Further, the moving die 44 enters from the outer member opening 22a toward the protruding portion 36. The movable die 44 is brought into the protruding portion 36 by the outer member opening 22a which may cause a decrease in the welding strength between the inner member 30 and the outer member 20. It is preferable that the inner member 30 be welded to the outer member 20 with high strength without forming an opening or the like in other portions.
The distal end surface 36t of the protrusion 36 is formed substantially parallel to the base surface 21. Therefore, by moving the movable die 44 in a direction substantially perpendicular to the moving direction of the support die 41, the movable die 44 can be brought into contact with the protruding portion 36. The interference between the support die 41 and the movable die 44 can be prevented. The simplification of the apparatus and the degree of freedom in design become high.
When the inner member 30 is welded to the outer member 20, the inclined surface portion 22 and the protruding portion 36 are held therebetween. Deformation of the inner member 30 and the outer member 20 during vibration welding can be suppressed. This enables the inner member 30 to be welded to the outer member 20 with high strength.
Example 2 ]
Next, a spoiler 10A of embodiment 2 is described with reference to the drawings.
Fig. 6 shows a spoiler 10A of embodiment 2, which corresponds to fig. 3B. The spoiler 10A of embodiment 2 is different from the spoiler 10 (refer to fig. 2) of embodiment 1 in the shape of the protruding portions 51, 52. The other basic structure is the same as that of the vibration damping mechanism of embodiment 1. The same parts as those of embodiment 1 are denoted by symbols, and detailed description thereof is omitted.
One protrusion 51 is formed in a substantially H shape. The 2 longitudinal protrusions 51a extending in the front-rear direction have the same shape as the protrusions 36 (see fig. 3B), and the lateral protrusions 51B are formed so as to connect the centers of the longitudinal protrusions 51 a. The contact area with the movable die 44 increases, and the rigidity of the vertical protrusion 51a is improved with respect to the amplitude direction of vibration welding, so that the support can be more reliably performed.
The other protruding portion 52 extends in the left-right direction. The protruding portion 52 extending in a direction perpendicular to the extending direction of the inclined surface portion 22 (see fig. 2) may also be referred to as a "protruding portion". The contact area with the movable die 44 becomes large, and the support can be made uniform in the width direction.
The spoiler 10A having the above-described protrusions 51 and 52 can also obtain the effects specified by the present invention.
The vibration welded molded article of the present invention is described by taking the tail gate spoiler as an example, but the present invention can be applied to other vehicle components. The present invention is also applicable to other applications than vehicle components, and is not limited to these embodiments.
The other members provided in the opening of the outer member of the vibration welding molded article may be provided with a camera, a duct, or the like in addition to the brake lamp, and are not limited thereto.
In addition, the embodiments can be appropriately combined. For example, a protrusion along the extending direction of the inclined surface portion and a protrusion extending in a direction perpendicular to the extending direction of the inclined surface portion may be formed on 1 second engaging surface portion. The distal end surface of the H-shaped or laterally long protruding portion may be formed substantially parallel to the base surface portion.
The present invention is not limited to the examples as long as the effects and actions of the present invention can be obtained.
The vibration welding formed product is suitable for the tail gate spoiler.
